In 2020, I invented a new bike gear: the new fixed gear.
The new bike transmission is designed for bicycles with muscle drive for public roads (highway).
The fixed gear has an intermediate shaft to which an additional pair of cranks with pedals is attached.
I made a valid model of a bicycle on a frame made of AISI 304 steel with the following gear ratio: (48/17) x (53/22) = 6.8. In inches it is 6.8x26 = 176.8 ".
In the preliminary run-in, the NewFixedGear weighing 17.5 kg was faster than my Polo & Bike fixed gear weighing 10.4 kg.
This season, testing of the project will continue.
I will be glad who will start making such devices for themselves and are ready to cooperate.
